3-position pneumatic actuator ball valve
pneumatic actuator
- Through research development and design XM series pneumatic actuators incorporate the latest technology materials and innovative idea. The product proudly boasts the following features.
- Full conformance to the latest specifications: ISO5211,DIN3337 and VDINDE-3854,NAMUR.
-
The extruding high intensity aluminum body possesses a honed internal surface coated with hard anode oxygenation for long life. Low coefficient of friction and swift performance.
-
Excellent compact and modernized construction along with multi specifications makes the selection both economic and beneficial.
-
All acting surface adopt high quality bearing resulting in low friction, high cycle life, and no noise
-
The two independent external stroke adjustment bolts can easily and precisely adjust ±5°at both open and close directions.
-
Same outline actuators have the functional modes of double acting and single acting (Spring -Return). The Spring-Return has the normally-open and normally-close styles.
-
Multi function indicator with NAMUR is convenient for mounting accessories.
-
Pre-compressed load spring is convenient for safe mounting and tear down procedures.
-
Die-casting aluminum pistons and end caps have high intensity and light weight.
-
Different O-rings materials are available for high and low temperature.
-
Solenoid valves are easily mounted without any connecting plank.

3-position Pneumatic Actuator
Two types of 3-position pneumatic actuators:0°-45°-90° type and 0°-90°-180° type
respectively. After the air comes into the cylinder from the air entrance”2”,the pistons' movements toward the ends would be limited by the auxiliary pistons mechanism. Thus the pistons would stay in the middle position The position of the mid position could be adjust to 20°,30°,50°, 75°and 95°,1 20°,1 30°,150°,1 75°etc by using the adjusting screws at each end of the surface.
